"It's time," Dinklage said during a new interview with Variety. "Story-wise, not just for all our lives. It's the perfect time to end it. Sometimes shows stay on a little too long, the jumping-the-shark thing."

The coming eighth and final season of "Game of Thrones" is scheduled to air sometime in 2019. Though the season will be the shortest yet (with only six episodes), each of the final episodes is reported to be longer than usual.

According to Dinklage, filming for this final season — which began in October 2017 — is about halfway done.

"It's the final season, and it's a long one so we're taking our time," he told Variety.
